DISHWASHER,

Application filed February 15, 1927. Serial No. 168,403.

This invention relates to a dish washer, and,

particularly to a construct-ion including a I tank provided with a cradle to carry the articles to be washed which are reciprocated through the liquid within the tank.

It is particularly desirable in this'art to provide amounting for the cradle permitting its free reciprocation and an operating handle therefor which is adapted to be'disposed substantially within the tank when the washer is not in use. It is also important to so construct the tank that the discharge or waste therefrom maybe eontrolledand any food particles or other matter caught and removed before the discharge and also to construct the waste valve or plug so that the same will operate to maintain the necessary liquid level within the tank cient washing operation.

The invention therefore has for an object to provide the tank with a swinging cradle having mounted, upon its hanger a sliding handle or operating lever adapt'ed'to be withdrawn from the tank when in position for op eration and to be replaced therein at other times. M

A further object of the invention is to provide an improved form of tank having a waste opening in connection wit-h a tubular plug controlling said opening and open at its upper end to est'abli'sh'a proper waterlevel relative to the cradle within the tank.

Another object of the invention is to provide an improved construction of a cradle con'iprising a frame of angle iron supported upon a yoke hanger and carrying gni de strips ouhvardly deflected in opposite directions soas to facilitate the introduction and-removal of a basket carrying the articles to be w: shed.

Other and further objects and advantages of the invention will be hereinafter set forth and the novel features thereof defined by the appended claims.

Like reference characters designate correfor the most efiisponding parts throughout the several figures-of the drawing.

While the invention is shown and described 1n connection with a dish washmg machine,

it is-capable of other applications and the form or size of the tank may be varied at will. As shown in Figures 1 and 2, the tank 10 is provided with a longitudinally curved bottom 11 which is substantiall concentric to the arc of travelof the cradli; within'the tank. This tank may be supported by any desired means such as the angle standards 13 at its corners, and is provided at its top With a partial cover 14 to prevent splashing of the water at the opposite ends and a back board 15. At the central portion of the rear of the tank a depending well 16 is formed from which a discharge or waste pipe 17 extends. i

The cradle may be suspended in any desired manner but preferably by means of a yoke hanger having the horizontal portion 18 upon which the cradle l2'rests and the vertical arms l9 formed at their upper ends with pivots 20 operating in bearings 21 upon thecover portion ltof the tank.:- This hanger may be formed of a rod 'of any desired cross section and is here shown as circular so as to receive the sleeve 22 carried by a face of thehandle bar or lever 23 provided at its free end with'ahandle 241; This sleeve is preferably formed with africt-ion fit uponthe rod so as to retain it in its elevated position and a or seat 22- to engage a pivot 20 when raised to retain the handle against freerotm tion in the operation of tl'iemachine. Such a construction permits the handle r0 be inserted mum machine when not in use so as to be out of the way and permit the free introduction of the articles into i I The cradle 1s specifically formedof an angle the cradle.

posite ends 28 so as to guide into position the wire or other form of basket 29 in which the dishes or articles to be washed are disposed. For the purpose of conveniently han dling'this basket it is formed with handles at its opposite sides.

Under many conditions it is desirable to provide means for heatlng the Water withm 12 supported of the frame and connected to V the guide strips 27 which are outwardly deflected at their opthe tank and maintaining the same at a proper temperature for most eflicient results and for this purpose a gas or other form of burner 31 may be disposed beneath the tank and supported at one end by'a bracket 32 from the Well 16 and at its opposite end from the tank. 7 7

For the purpose ot'controlling the waste opening 17 a tubular overflow valve 33 is provided and preferably disposed in a chamber 34 at the rear of the tank which co nr unicates with a body of liquid therein through the Well 16 which is providedwith a removable reticulated basket 35 in order to retain any solid material in the liquid. This tubular plug tits at its lower end in a seat 36 and is open throughout its length so as to establish the desired Water level Within the tank as it permits an overflow of the Water therein when itreaches such elevation. The plug is guided in its vertical movement by the loops 37 formed at the ends of Wall. 37 and provided at its upper end with a flexible connection 38 having a bail 39 engaging the tube and adapted at its upper end to be engaged with either of a plurality of hooks d0 upon the back 15. As shown in Figure 2, when the plug is seated to close the Waste opening the connection 38 is slack, and When the plug is open it is sustained by this connection upon the upper hook 4L0.

The operation of the invention Will be apparent from the foregoing description from which it will be seen that the construction of tank provides means for securing an etficient ashing action by the movement longitudinally therein of the liquid and basket While the cover of the tank prevents splashing and the drain Well and plug provide While the specific details of construction have been shown and described, the invention is not confined thereto as changes and al terations inbe made without departing irom the sp t thereof as deiinedbythe appended claims.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is p 1. In a dish washer, a tank, a hanger having vertical arms pivoted at the upper portion of the tank, a cradle car ied' by the hanger, and a handle slidingly mounted upon one of said arms for adjustment relative to the cradle.

2. In a dish Washer, a tank, a hanger having vertical arms pivoted at the upper portion of the tank, a cradle carried by the hanger, and a handle lever having a sleeve slidingly embracing one of said vertical arms.

3. In a dish Washer, a tank, a hanger hav ing vertical arms pivoted at the upper portion of the tank, a cradle carried by the hanger, a handle lever having a sleeve thereon slidably engaging one of the vertical arms, and means for retaining said sleeve against rotation upon the hanger.

In testimony whereof I aiiix my signature.

JOHN JIRETZ, ea.
